Abstract
By using 4-nitroimidazole as a raw material in condensation with 2-amino-3,5-dinitro-6-chloropyridine and 2, 6-chloro-3-nitro-pyridine, 6-(4-nitro-imidazol-1-yl) -2-amino-3,5-dinitro-pyridine (1#) and 6-chloro-3-nitro-2-(4-ni-tro-imidazol- 1-yl)-pyridine(3#) were synthesized with yields of 65% and 52% respectively. The synthesis of 3-nitro-2-(4-nitro-imidazol-1-yl)-pyridine (2#) was optimized by this method with a yield of 85% . Further azidation of compound 3#was carried on to give 5-azido-6-nitrotetrazolo [1,5-a]pyridine(4#). The structures of these compounds were characterized by 1 H NMR,13 C NMR, MS and elemental analysis. Thermal behavior of compound 1# was studied by TG and DSC. Results show that the initial decomposition temperature of compound 1# was 221. 83℃ , the total decomposition heat 302. 65 kJ/mol, while its mass loss of 71. 84% takes place at the temperature of 209. 17 ~ 398. 67 ℃ .关键词
